A T47 threaded bottom bracket built to run a Praxis M30-compatible 28/30mm crank spindle, supplied with the spacers and insert needed to set it up correctly.

Highlights

  • Machined aluminium cups thread directly into a T47 bottom bracket shell
  • Fits BB shells from 68mm to 100mm wide
  • Bearings are easily serviced or replaced
  • Includes a sleeve between the cups to keep out dirt and protect internal cables and hoses
  • Comes with the spacers and 28mm insert needed for a Praxis M30 crank

What's included

BB cups with bearings, two silicone dust seals, two 0.5mm crank spindle spacers, two 1.0mm crank spindle spacers, one 2.5mm crank spindle spacer and one 28mm insert.

Threading and installation

Like standard BSA threaded cups, the drive side cup is left-hand thread and the non-drive side is right-hand thread. Use a quality grease on steel or aluminium shells, and an anti-seize compound on titanium shells.

Fitting

Tune's workshop can fit this bottom bracket for you — the right cup tool and torque setting matter, especially on a press-fit or T47 shell.

Compatibility & fit

Fits T47 threaded frames with shell widths from 68mm to 100mm, and Praxis M30-compatible 28mm or 30mm diameter crank spindles.

Wheels Manufacturing backs this bottom bracket with a 1 year warranty against manufacturing defects, plus 30-day returns. For warranty support, return the product to Tune Cycles and we'll manage the claim with Wheels Manufacturing's Australian distributor.
